A compound found in green tea may trigger a cycle that kills oral cancer cells while leaving healthy cells alone, according to Penn State food scientists. The research could lead to treatments for oral cancer, as well as other types of cancer.

This fungal colony, in association with a few others, was grown on SDA and appears to be an antibiotic producer. The compounds that it's producing appear orange and red. The colony grew and began producing compounds on the agar after five days incubation at 30 degree Celsius. This plate is part ...

Paenibacillus species have been isolated from a wide variety of sources including soil, water, the plant rhizosphere, plant materials, food, fodder, faeces and diseased insect larvae. They are facultative anaerobes or strict aerobes and mostly motile, endospore forming rods. This is the first ti...

Bacteria may not have brains, but they do have memories, at least when it comes to viruses that attack them. Many bacteria have a molecular immune system which allows these microbes to capture and retain pieces of viral DNA that they have encountered in the past, in order to recognize and destro...

Cleveland Clinic researchers have, for the first time, linked trimethylamine N-oxide (TMAO) – a gut metabolite formed during the digestion of egg-, red meat- or dairy-derived nutrients choline and carnitine – to chronic kidney disease.

TMAO has been linked to heart disease already, with blood...

Rob Knight is a pioneer in studying human microbes, the community of tiny single-cell organisms living inside our bodies that have a huge — and largely unexplored — role in our health. “The three pounds of microbes that you carry around with you might be more important than every single gene you...

More than 600 years after the bubonic plague wiped out about half of Europe, scientists still don’t fully understand how bacteria that cause the disease travel from the site of a fleabite to the lymph nodes, where the rampage truly begins.

By the dawn of the 19th century, tuberculosis had killed one in seven of all people that had ever lived. Doctors believed it was hereditary, but had begun to observe that fresh air and outdoor living could sometimes change the course of the illness. Physician and TB patient Edward Trudeau was co...

Pictured here are blue colonies of Methicillin-resistant Staphylococcus aureus (MRSA) growing on Remel Spectra MRSA medium. Spectra media contains a chromogen that yields a blue color as a result of phosphatase activity. The phosphatase enzyme is present in many staphylococci, including Staphylo...
